Ultrasonic Rear Parking Assist (Urpa) - Cadillac 2003 Seville Owner's Manual

Ultrasonic Rear Parking Assist
(URPA)
Ultrasonic Rear Parking Assist can help you to
determine how close an object is to your rear bumper
within a given area, making parking easier.
If children, bicycles, or pets are behind your
vehicle, RPA won't tell you they are there. You
could strike them and they could be injured or
killed. Whether or not you are using URPA,
check carefully behind your vehicle and then
watch closely whenever you back up.
The URPA display is
located inside the vehicle,
above the rear window.
It has three color-coded
lights that can be seen
through the rearview mirror
or by turning around.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system comes on,
the three lights on the display will illuminate to let you
know that the system is working. URPA senses
how close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper. When you shift into REVERSE (R) and
an object is detected, the following will occur in
sequence depending on the distance from the object:
At 5 feet (1.5 m) a chime will sound and one
amber light will be lit;
at 40 inches (1
.O
m) both amber lights will be lit;
at 20 inches (0.5
m)
a continuous chime will sound
and all three lights (ambedambedred) will be
lit; and
all three lights (amber/amber/red) will flash.
at 1 foot (0.3 m) a continuous chime will sound and
URPA can detect objects 3 inches (7.6 em) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.
